Braxton Hicks or contractions

Jessie
I'm having VERY strong mesntral like cramps they aren't regular but seem to keep happening over the last few hours. I called the Dr. on call and she told me if I was worried I was having contractions to go to the hospital and get checked out but I'm waiting because if it's nothing and normal I really don't want to go to the E.R especially if it's non emergency related. Oh and I'm 34+5 today
